Neutron-scattering experiments demonstrate that the Ce-ions in Ce1-xScxAl2 are trivalent up to x = 0.4, undergo a change into an intermediate-valence state between x=0.4 and 0.5, and show, upon further increasing x, a continuous increase of valence, eventually reaching a completely demagnetized state of Ce for dilute (Ce,)Al2 alloys.
